Some caveats about this data:
This data has not been quality controlled, and should be considered preliminary. CERTIFIED climate data is available from the National Climatic Data Center or from the Midwestern Regional Climate Center.
Lack of data for a period of time may be the result of a communications failure, and the observations may still be available from one of the centers above.
Weather described as "fair" means that no clouds were observed below
12,000 feet. This is a limitation of all automated stations, which make up nearly all observations in the list.
Sky conditions give the general state of the sky, and the height of each cloud layer. Heights are given in hundreds of feet (e.g. 120 is 12,000 ft; 012 is 1,200 ft., 001 is 100 ft.). State of the sky is divided into SKC (sky clear), CLR (clear below 12,000 ft), FEW (2/8 or less cloud cover up to that height), SCT (3/8 through 4/8 of cloud cover up to that height), BKN (5/8 through 7/8 of cloud cover up to that height), OVC (sky cloudy), and VV (vertical visibility -- clouds obscured by precipitation or obstructions to vision).
Weather "in the vicinity" indicates within 5 to 10 miles of the station.
